Yoon Ji Sung has revealed the trailer for his special comeback.

After starting out as a solo artist, Yoon Ji Sung presented himself as a ballad singer who sings of thoughtful moments and seasonal changes. In this special album, he presents another meaningful story, but one dedicated only to himself and his diary. 

In the video, Yoon Ji Sung talks about going on a trip by himself, wishing it to be a "slow journey" and pondering about what will fill up his diary in his 20's. At the end, he says: "but at the end of this diary, I hope it says, 'and they lived happily ever after that.""
